Why do you need to replace the pump in your dishwasher? Execution algorithm, errors and tips

Replacing the pump in a dishwasher is required in cases where it does not drain the waste liquid. This can be determined by observing the operation of the device. If you have certain skills, you can remove the old part and install a new part yourself. The article describes how to do this.

How to understand that the pump is broken

First of all, you need to understand how to check the circulation pump of a dishwasher. To do this, you need to observe how the device works at the moment when it is necessary to drain the waste liquid. If it does not go down the drain and remains in the chamber, this is the main sign of a breakdown.

On the other hand, the same symptom may indicate a clogged drain hose or filter. Therefore, before starting repairs, you should disconnect the unit from the network, turn off the tap, and then disassemble and check each element. They are washed under the tap with detergent, then put back in place and checked whether this helped solve the problem.

But if the water still does not leave, and all elements of the drainage path are clean, it is the pump that needs to be replaced. To do this, it is not necessary to understand the differences between a recirculation and circulation pump, or the features of a particular device. Replacement is carried out according to the general rules described in the next section.

Step-by-step instruction

Replacing the pump in a Bosch dishwasher or other models begins with unplugging the device and turning off the tap. The main steps are:

1. All dishes, as well as baskets and filters, are removed from the chamber.
2. The remaining liquid is drained from the pan. If you can’t get close to the filter, simply remove the water with a regular rag.
3. Unscrew each screw and remove the cover. Next, you need to dismantle the grate above the drainage hole and the tube connected to the sprinkler. Each part is fixed with a self-tapping screw, which can be unscrewed with a screwdriver.
4. Under these elements there is a plastic or metal panel. This can also be removed by opening the latches or unscrewing the bolts.
5. Before replacing the pump in the dishwasher, it is necessary to remove the insulator material, that is, a piece of felt or foam rubber.
6. At this stage, you need to tilt the unit away from you and thoroughly wipe the surface with a rag. If the pallet is in the way, the front screws securing it should also be unscrewed.
7. It is clear how to check the dishwasher pump. All that remains is to find him. After the described steps, you can see the part in the intended place, as in the photo. A tube, cord and water sensor are connected to it. Each of these elements is carefully dismantled.
8. The pump that needs to be replaced resembles a similar part in a washing machine.
9. The old part is removed and a new one is put in its place. Next, you need to assemble all the devices in reverse order. To make the work easier, it is recommended to first photograph the assembly from different angles.

After replacing the dishwasher circulation pump, all that remains is to make sure that the device is working properly. To do this, the pallet is screwed back onto the screws, insulation material and other parts are installed.

Plug the dishwasher into an outlet and pour some water into the tray. Next, run the program with the drain option and check whether the waste liquid leaves the chamber. In this case, you must follow safety precautions and do not touch metal parts so as not to receive an electric shock. Also, do not pour water into the container under the pump, as this will lead to incorrect sensor readings.

Thus, replacing the drain pump in a dishwasher can be done independently in just an hour. This will require common household tools. But if you have doubts about the cause of the breakdown, it is better to contact a service center - repairing it yourself at random can lead to even greater problems.
